Application filed June 9, 1903. Renewed September 28, 1905, Serial No. 230. 260.

My invention relates to improvements in a combined clutch and transmission-gear; and one ob ect that 1 have in view is to combine in one structure a two-speed or diil'erential transmission-gear and a clutch device adapted to control the starting and stopping oi the machine to which the new device is applied.

A further object of the invention is to compactly arrange the several parts with a view to making them take up a very small amount of space on a motor-vehicle or any other form of machine or apparatus, and, furthermore, to simplify the construction, cheapen the cost of manutact 're, and promote the eliiciency of operation.

Further objects and advantages of the in.

vention will appear in the course of the subjoined description, and the novelty will be defined by the annexed claims.

Reference is to be had to the accompanymg drawings, 'rorming a part Oftl'US spec hcation, in which similar characters of reference indicate corresponding parts in' both the figures.

Figure 1 is a vertical sectional elevation through a combined clutch and ditlerential speed-transmission gear constructed in accordance with my invention, and Fig. 2 is an elevation showing the trains of gears between the driven member and the shift able intermediate member of the device.

In the drawings 1 have shown my impro ved dcviceas especially adapted for use in corn nection with certain. parts of a motor-cycle,

wherein A indicates a portion of a gear-casing which is provided with an end wall a and with an extension a in the term of an annular flange. The end wall of the gear-easing is 'provided with a bearing-sleeve I), which noouter or working far of win :l i ange is made rone-shapml, as indicated at 7. This disk is provided with a hub 8,which is fitted on the shaft B, and to one side or face oi the disk is made last a spur-g ar 9. The spur-gear is coi'iccntrie with the driving member 5, and it is shown as being secured iirmly to. said driving member by rivets ill; but it will be understood thatthe spur-gear and the disk 5 may be made in one piece, if desired. According to my invention it is essential that the disk 5 and the gear 9 be made last one with the other, so to rotate simultaneo sly, and this disk with gear practically constitute one part which terms the driving element of the improved device. This driving element is made fast with the shaft B by any suit-able mechanical contrivance such, for example, as the key 1] p ll designates the driven member, which is provided with an eiongated sleeve or hub 13, the latter being titted loosely on the projecting end portion of the shaft B and adapted to turn freely thereon. The driven member is of less diameter than the driving member 5., and it carries a series of spur-gear pinions 14, which are idly mounted on a series of studs or pins 15, the latter being made integral with the driven member 12 or attached in suitable way therel o. The series of gear-pinions 14 are disposed to have intermeshing engagement with the teeth of the gear 9, which rotates with the driving member 5, as shown by Fig. 2, and this driven member 12is adapt ed to be shifted lengthwise of the shaft B for a limited distance by means of a lever 16. Said lever is provided with a fork 17, which.

having :1 laterally-extending flange 6, the

embraces the hub or sleeve 13 of-the driven member and operatively connected therewith by suitable projections 18 of the fork (see dotted lines in Fig. 1) fitting in. an annular groove 19 of the sleeve. Said lever 16 is fulerumed by a iin or bolt- 20, attached to a supporting-shard; 2l,that is fastened in alug 22 ot the gear-casing A. 7

It is obvious that the lever 16 may be shifted in one direction or the other for the purpose of moving the driven member 12 on the shalt B laterally with respect to the driving member 5; but the shiftable adjustment ol said driven member 12 (lees not disengage the series of gear-pinions l4- irom the spur-gear t), which is fast with said driving member 5. I

member which is made in the form of a ring and arranged to fit circumferentially and loosely on the driven member 1.2-, said inter mediate shil'table member having a coopera tive relation to the driving member 5 and, to the cup 26, which is fast-with the extension a of the gear-case. The intermediate member 23 is provided with two flanges 24 25, the same being integral with the member 23 and occupying the positions indicated more clearly by Fig. 1. The flange 2d of the intermediate member is provided with beveled inner and outer faces, thereby producing a conical portion on the shiltable member, whereas the flange 25 is in the form of an annulus which is concentric with the axis of the shaft B. This annular llange 25 is provided with a continuous series of internal gear-teeth 27, the same being presented in opposing relation to the teeth of the gear-pinions 1. 1, which are joun naled on the driven member 12, whereby the teeth 27 of the inti-zrmediatc member 23havc intermeshing engagement with the series of pinions on the driven member 12. From this description it will be seen that the shiftable intermediate member 23 is constructed with an internal gear and with a conical flange, the latter adapted to serve as the tomale member oi a clutch, because it is pre sented into cooperative relation to the surface 7 on the flange 6 of the driving member 5, said flanged driving member also serving as the male member of a clutch. The internally-toothed flange 25 of the shit'table member 23 fits within the conical male flange 6 of the driving member 5 in order that the parts may occupy a may compact relation, whereas the comcal flange 24 of said intermedlate member 23 is presented between the.

surface 7 of the driving member 5 and the internal tapering surface of. the cup 26. The driven member 12 fits loosely inside of the annular flar re 25 of the intermediate member 23 in order that one face of said driven member 12 may engage near its periphery with the inner edges of the series of gearteeth 27, thus insuring the movement of the member 23 with the member-12 when the latter is pressed in an inward direction by the proper movement of the lever 16. The HIOVOII'IOTlt of the intermediate member 23 with the driven member 12 when the latter is shifted in an outward direction is secured by the employment of a taco-ring 2b, the latter being applied laterally to the member 23 and This tacormg is thus made last with the intermediate member, and it projects inwardly therefrom in order to have overlapping engagement with the shil'table member 12, whereby the edge portion of this shil'table member is confined between the series of gear-teeth 27 and the face-ring 28, as clearly shown by Fig. 1.

The cup 26 hasan external annularsurface, and it is of such diameter that it on who titted snugly within the extension (1 of the gearease. This cup is adapted to be held stationary within said case extension by any corresponds to the external taper of the conical flange 24 of the intermediate'member 23, whereby said flange 2-i is adapted to have tight frictional engagement with the cup when the intermediate member 23 is shifted with the driven member 12 in an outward direction. h'lotion is transmitted from the driven member 12 to any proper part by a suitable transmitting mechanism, and Fig. 1 this member 12 is shown as having a gear 32, adapted to drive a train of gearing, a sprocket chain, or, the like.

It will be understood that my improved clutch and gear may be used'in connection with any kind of machinery.

The operation of the invention may be described as follows: Assuming that the shaft B is in motion, the member 5 and its earQ rotate with said shaft at all times, while the driven member 12 and the intermediate member 23 loosely surround said shaft, so as to remain at rest or be driven from said member 5 or the gear 9, according to the adj ustments of the parts. The lever 16 may readily be operated to move the members 12 23 either inwardly or outwardly; but when said members 12 23 occupy a middle position lmtweon the driving member 5 and the cup the clutch mechanism is free or released, so that the driven member 12 remains at'rest or in an idle osition, thus unclutching the shaft B from t e device which it is desired to drive-such, for exam le, as the driving wheel of a motor-vehicl e. The operation of the lever 16 to shift the driven member 12 in an outward direction causes the edge portion of said member to engage with the face-ring 28 and to move the member 23 in a similar direction, so that the external surface of the conical flange 24 will have tight frictional engagement with the stationary cup 26, thereby clutching the intermediate member 223 with said cup 26 and holding said intermediate member in a fixed or locked condi- Lion. The motion ol'the spur-gear 9, which rotates with the member 5 and the shaft B, operates to turn the series of gear-pinions 14-, and the train of gearing thereby propels the driven member 12 at slow speed. it it is desired to drive the parts at a hi her speed, the lever 16 is operated to nove t 1e member 12 and the intermediate member 23 in an inward direction, so that, the internal face of the conical flange 24 will have tight frictional engagement with the face 7 on the male cone 6 ol' the driving member 5. This 1 0 adjustment brings the intermediate member 23 and the driving member directly into engagement, and the series of ear-pinions 14 are thuslocked fast with the c riveri member 12 by the toothed engagement of said gear-pinicns with. the spur-gear 9 and the in ternally-to0 thedflaii c 25 of the intermediate member, whereby tr e driving member the intermediate member 23, the driven member 12, and the gears 9 14 will all rote at a relatively higher speedbecanse the parts are clutched directly together.

My improved construction of clutch and transmission gear provid s very com form of mechanism, wherein parts disposed to take up a very small amount of room, and these parts are simple in construction, easy of assemblage and operation, and they are cheap of manufacture. it is evident that the cup 26 may easily be disconnected from the gear-case for the purpose of permitting access to be obtained to any oi the working parts in case it is desired to rcpair or inspect the same.
